“Sometimes we get caught in situations when we need direct solutions without figuring things out in more efficient manner. For instance microcontrollers and pin count. When we need more pins, we start looking for bigger MCU even if processing power …
“For some unknown reason, the OSCCAL value sometimes gets erased during programming of the chip. Without the OSCCAL value, the PIC will not run at the optimal 4MHz. For most projects, this is not a problem. Some of my PICs …
“Apparently Ive come up to a point, when I want to do firmware upgrades for my home automation over-the-air. Since Im using nRF24L01 dongles, I decided to write a bootloader for that. While my pet antares project is slowly progressing …
“RS232 is one of the most used, easy to develop and easy to apply communication protocol. We generally encounter to this standard at the MCU applications. But it has some restrictions. It allows us to use maximum 15 meters cable …
“Here we are going to interface a MSP430 Launchpad with a RS485 transceiver chip like MAX485 and communicate with an x86 PC. Serial(TTL) or RS232 protocol is fine if you are planning to communicate over short distances of a …
“SCADuino is a 3D printable version of the Breadboard Arduino at Arduino.cc. Using OpenSCAD and the SCADBoard library it is easy to create a 3D printable breadboard like the Breadboard Arduino.”
“Attiny85-based device to enable and disable write-protection on any SD card. “
“A supercheap Arduino-based 2-wheel robot for robot workshop purposes. A collaboration by various Bristol Hackspace members. Designed by Richard Sewell.”
“The Raspberry Pi is an amazing 35 dollars mini-computer. It allows you to do everything you could do with a regular Linux computer (Connecting to the internet, watching videos, launching applications, …) but also to interact with the world surrounding it …
“I was getting a bit frustrated with my old lab power supply, a Manson EP925. I bought it second hand many years ago during my student years. The problem with it is that it has only one output. For many …
